Question: What is the molecular shape of BF3 according to VSEPR theory?

Options:

Correct Answer: Trigonal planar

Solution:

BF3 has three bonding pairs and no lone pairs, resulting in a trigonal planar shape.

What is the molecular shape of BF3 according to VSEPR theory?

What is the molecular shape of BF3 according to VSEPR theory?

Step 1: Identify the central atom in BF3, which is boron (B).
Step 2: Count the number of bonds boron forms with fluorine (F) atoms. BF3 has three F atoms bonded to B.
Step 3: Determine the number of lone pairs on the central atom (B). In BF3, there are no lone pairs on boron.
Step 4: Use VSEPR theory to analyze the arrangement of the bonding pairs. With three bonding pairs and no lone pairs, the shape is determined.
Step 5: Conclude that the molecular shape of BF3 is trigonal planar.
